[Logcheck-devel] Bug#494740: first debian openvz 2.6.26 bugs

[Michel Messerschmidt]

Sorry for the late reply, but somehow I haven't received any mail yet
(just saw the answers on the web interface).

Exactly.


I tried it again with 2.6.26.2 kernels on 686 and amd64 machines but the 
problem persists.

With the kernel from linux-image-2.6.26-1-openvz-686_2.6.26-2_i386.deb
on the nfs server I get the same error as before.
It seems that nfsd and nfs fail to load:
# lsmod | egrep 'nfs|rpc|lockd|statd|idmap'
auth_rpcgss            34752  0 
lockd                  55016  0 
nfs_acl                 3680  0 
sunrpc                163904  6 auth_rpcgss,lockd,nfs_acl

But NFS works if I use the non-openvz kernel from
linux-image-2.6.26-1-686_2.6.26-2_i386.deb.



Looking at the nfs client, I also get an error with the kernel from 
linux-image-2.6.26-1-openvz-amd64_2.6.26-2_amd64.deb:

With a non-openvz kernel there are also no problems on the client:
# lsmod | egrep 'nfs|rpc|lockd|statd'
nfsd                  248360  4 
auth_rpcgss            47520  1 nfsd

lockd                  68560  2 nfsd,nfs
nfs_acl                 7552  2 nfsd,nfs
sunrpc                197608  16 nfsd,auth_rpcgss,nfs,lockd,nfs_acl

(BTW why is the nfsd module loaded on a client-only machine?)
